  in 
  the 
  male 
  the 
  hind 
  femora 
  and 
  tibiae 
  are 
  similar,

  the 
  fifth 
  joint 
  

   is 
  tri-dentate

  The 
  habitat 
  of 
  this 
  species 
  does 
  not 
  seem 
  to 
  extend 
  much 
  beyond 
  

   the 
  Cape 
  District, 
  but 
  I 
  have 
  received 
  it 
  also 
  from 
  Clanwilliam.

  This 
  species 
  is 
  very 
  closely 
  allied 
  to 
  the 
  preceding 
  one, 
  being 
  very 
  

   similar 
  in 
  shape 
  and 
  structure, 
  but 
  the 
  elytra 
  are 
  reddish 
  brown 
  in 
  

   both 
  sexes, 
  and 
  the 
  hind 
  legs 
  of 
  the 
  male 
  are, 
  as 
  a 
  rule, 
  black, 
  but 
  I 
  have 
  

   occasionally 
  seen 
  some 
  small 
  males 
  with 
  red 
  legs 
  ; 
  there 
  are 
  no 
  scales 
  

   on 
  the 
  prothorax, 
  along 
  the 
  outer 
  margin, 
  or 
  on 
  the 
  disk 
  which 
  has 
  a 
  

   much 
  deeper 
  median 
  furrow 
  than 
  in 
  P. 
  obscurepurpurea 
  ; 
  the 
  scu- 
  

   tellum 
  is 
  slightly 
  shorter, 
  the 
  sulcate 
  parts 
  of 
  the 
  elytra 
  are 
  almost, 
  

   identical, 
  but 
  the 
  scales 
  which 
  are 
  also 
  white 
  in 
  the 
  male 
  and 
  yellow 
  

   in 
  the 
  female 
  are 
  not 
  so 
  closely 
  set, 
  and 
  do 
  not 
  form 
  a 
  band, 
  except 
  

   at 
  the 
  rounded 
  apical 
  part 
  ; 
  under 
  side 
  and 
  legs 
  as 
  in 
  P. 
  obscurc- 
  

   purpurea.

   all 
  round, 
  and

  round 
  scaly

  brownish 
  red, 
  opaque, 
  and 
  having 
  a 
  small 
  

   patch 
  of 
  yellow 
  scales 
  under 
  the 
  humeral 
  callus, 
  near 
  the 
  outer 
  

   margin 
  ; 
  propygidium, 
  abdomen, 
  and 
  pygidium 
  clothed 
  with 
  yellow 
  

   scales, 
  whitish 
  on 
  the 
  abdomen 
  ; 
  legs 
  black 
  ; 
  clypeus 
  sharply 
  

   acuminate 
  and 
  with 
  the 
  two 
  apical 
  teeth 
  reflexed 
  ; 
  head 
  and 
  prothorax 
  

   rugose, 
  clothed 
  with 
  somewhat 
  long 
  and 
  dense 
  flavescent 
  hairs 
  and 
  

   somewhat 
  distinctly 
  grooved 
  longitudinally 
  in 
  the 
  middle, 
  the 
  latter 
  

   very 
  obliquely 
  attenuated 
  laterally 
  in 
  the 
  anterior 
  part, 
  and 
  nearly 
  

   parallel 
  from 
  there 
  ; 
  scutellum 
  very 
  long 
  and 
  sharp, 
  and 
  clothed, 
  

   except 
  at 
  the 
  base, 
  with 
  dense 
  yellow 
  scales 
  ; 
  elytra 
  a 
  little 
  ampliated 
  

   laterally 
  past 
  the 
  humeral 
  part, 
  and 
  attenuated 
  from 
  there 
  towards 
  

   the 
  apex 
  ; 
  humeral 
  callus 
  strongly 
  developed, 
  scarcely 
  sulcate. 
  

   except 
  near 
  the 
  base, 
  but 
  not 
  prolonged 
  into 
  a 
  rounded 
  costa,
